3 Claims.

The invention relates to improvements in horses such as are usedA by carpenters, masons.

and other artisans as a work support or for the support of scaffoldings, platforms, and the like, and the primary object of the invention is to provide a horse of this character which can be collapsed so as to occupy a minimum of space in transportation or storage, and which when set up, will be firm and rigid in service.

Other important objects and advantages of the invention will be apparent from. a reading of the following description taken in connection with the appended drawings, wherein for purposes of illustration a preferred. embodiment of the invention is shown.

In the drawings:

Figure 1 is a general side elevational View showing the horse in operative position and showing the legs folded into collapsed position in dotted lines.

Figure 2 is a top plan view of Figure 1.

Figure 3 is an end elevational view.

Figure 4 is a fragmentary top plan view showing a pair of the legs in partially folded condition.

Figure 5 is an end elevational View of the horse showing the legs partly collapsed toward each other preparatory to folding them into the dotted line position shown in Figure 1.

Figure 6 is a fragmentary enlarged transverse vertical sectional view taken through Figure 1 along the line 6 6.

Figure 7 is a top perspective view of one of the compound hinges.

Referring in detail to the drawings, the numeral 5 generally designates the horse which comprises the usual upper horizontal rail 6 which is of generally rectangular cross section, but provides on opposite sides adjacent each end with beveled notches into which the upper ends of the pairs of legs 8 are adapted to extend while the legs are in the expanded operative positions shown in Figures 2, 3 and 6 of the drawings.

The pairs of legs 8 are similar, each being composed of two relatively wide fiat vertically elongated generally rectangular cross section plates which have their lower ends inwardly beveled as indicated by the numerals 9 'in Figure 5 of the drawings to atly engage the door or other supporting surface when the legs are in expanded position. The upper ends of the legs are oppositely beveled as indicated by the numerals I0 to be flush with the upper surface of the rail 6 when the legs are in the expanded condition.

To keep thelegs of each pair in expanded position a conventionally available form of leg spreading linkage generally designated II may be employed and attached to the inner surfaces of the legs by brackets I2 as indicated in Figure 6 of the drawings. When the central portion of the linkage is brought above center the linkage may be collapsed upwardly as indicated in Figure 5 of the drawings to permit the legs 8 to approach each other from the expanded position.

MountingY the pairs of legs on the rail 6 are the combination hinges which are generally designated I3 and which are illustrated in detail inFigure 7 of the drawings, the compound hinges being similar in construction but reversed in arrangement at theopposite end of the rail 6. The hinge arrangement shoWn in Figure 7 corresponds to the left hand hinge arrangement in Figures 1 and 2 of the drawings. Each compound hinge comprises a plain rectangular plate I4 having hinge pin barrels I5 at one end thereof accommodating a hinge pin I6 which passes through an elongated hinge pin barrel I'I projecting from the adjacent end edge of a second plain plate I8 which is also rectangular in form.

The second plain plate I8 has inwardly leading flanges I 9 which conform in width and height with the bevel of the notches 'I in the sides of the rail 6 and are provided with holes 20 to accommodate screws or other securing means to hold the flanges ush on the beveled surfaces of the said notches. Triangular right angular eXtensions 2l on the opposite ends of the anges I9 are provided to engage the end walls of the beveled vnotches 'I in protective relation thereto and to assist in the strength and rigidity of the structure.

The rst plain plate I4 has on its opposite side edges centralized pin barrels 22 carrying hinge pins 23 which pass also through longitudinally spaced pin barrels 24 formed on the adjacent edges of the wings 25.

The wings 25 correspond in lengths to the widths of the upper ends of the legs 8 whose inner surfaces they conformably engage, holes 26 being provided in the wings to accommodate means for securing the wings to the legs, with the reinforcing and wear-resisting ears 21 formed on the opposite ends of the wing plates engaging the edges of the legs.

From the foregoing it will be evident that the screws or the like 28 traversing' the inwardly angulated plates or flanges I9 on the second plain plate I8 secure the compound hinge on the rail 6, and that the wings 25 secure the legs of the particular pair to the first plain plate Ill,

and enable the legs to swing laterally relative to this plate. It is also evident that the hinge connection of the first plain plate I4 to the second plain plate I8 enables the laterally swinging legs, limited in their relative movement only by the presence of the locking linkage II, to swing on the axis of the hinge pin I6 relative to the rail 5 to which'the plain plate I8 is aiiixed. By reason of these arrangements the pairs of legs can be folded parallel under the rail 6 when swung from the locked fully operated position illustrated in Figure 6 of the drawings, upon release of the linkage II, first to the intermediate position illustrated in Figure 5, and then longitudinally inwardly to the dotted line position illustrated in Figure 1, wherein the device of the invention occupies a minimum of space for transportation and storage purposes.

Although there is shown and described herein a preferred embodiment of the invention, it is to be definitely understood that it is not desired to limit the application of the invention thereto except as may be required bythe scope of the subjoined claims.

Having described the claimed as new is:

1. A collapsible horse comprising a normally horizontal rail formed with pairs of inwardly beveled notches in the opposite sides of the ends of said rail, pairs of normally upwardly converging ground engaging legs having their upper ends normally recessed in said notches, and compound hinges securing the legs to the opposite ends of said rail, said compound hinges comprising components providing for laterally swinging the legs of the pairs toward and away from each other invention, what is and providing for swinging the pairs of legs in laterally inward directions into substantial parallelism beneath said horizontal rail, said compound hinge comprising a first plate, a second plate having an end thereof hinged to an end of the rst plate, said second plate underlying said rail between the beveled notches, converging vflanges on the opposite sides of said second plate engaging the beveled surfaces of the notches, means securing said converging flanges in place, said first plate having wing plates hinged on the opposite sides thereof, means securing said wing plates to the inner sides of the upper ends of the pairedlegs, said wing plates being arranged to overlie said converging flanges within the notches when the legs are in operative spaced position.

2. A compound hinge of the character described comprising first and second plates, means hinging an end of said first plate to an end of said second plate, wing plates, means hinging said wing plates to opposite side edges of said first plate at right angles to said first means, attaching flanges projecting on one side of said second plate from the side edges of said second plate.

3. A compound hinge of the character described comprising rst and second plates, means hinging an end of said rst plate to an end of said second plate, wing plates, means hinging said wing plates to opposite side edges of said first plate at right angles to said rst means, attachingflanges projectingl on one side of said second plate from the side edges of said second plate, and lateral ears on the opposite ends of said wing plates. t
